tnCart WT1.02d This is just swapping the port numbers in the cst file. I simplified it because I don't know what caused it not to work. I have created 3 types of files. Runs at 27 MHz on-board(UMA module asynchronous). tnCart_WT102d_27MHz_async.fs Runs at 27 MHz on-board. tnCart_WT102d_27MHz.fs Runs on MSX 3.58 MHz clock(Boot loader reboots repeatedly and MSX may not boot). tnCart_WT102d_3_58MHz.fs
